In order to investigate in detail the hydrodynamics of the fluidized
bed, the boiler was very well equipped with numerous
pressure and temperature measurement taps located inside of the
furnace at 0.2 m (10 pressure and 13 temperature measurement
taps), 1.2 m (4 pressure and 8 temperature taps), 5 m (4 pressure
and 8 temperature taps), and 35 m (3 pressure taps) above the air
distributor. Furthermore, there were numerous pressure and temperature
measurement taps in the downcomers and in the loop
seals.
